Volumetric Combustion Diagnostics

Abstract

This two-year project is aimed at establishing advanced diagnostics techniques for obtaining volumetric measurement of key combustion properties. The proposed techniques are designed to generate instantaneous volumetric (i.e., three-dimensional, 3D) data without scanning or raster, and thusly to enable measurement rate in the multi-kilohertz range, directly addressing a key experimental need identified in the BAA. Six specific topics have been investigated during this project: 1) the establishment of a unified framework for volumetric tomography, 2) the investigation and validation of Volumetric Chemiluminescence imaging (VCHEM), 3) the investigation and validation of Volumetric Laser Induced Fluorescence (VLIF), 4) the investigation and validation of Volumetric Particle Image Velocimetry (VPIV), 5) the use of fiber bundles in volumetric tomography, and 6)algorithms for data Analysis and post processing.
